NEC Nexa Solutions launches generative AI voice agent for automated calls

NEC Nexa Solutions has launched a new automated telephone response service, ‘Interactive Voice AI Agent Powered by DEN. Ai’, which utilizes generative AI to handle initial call reception for companies and local governments. Unlike traditional menu-based systems, this service allows users to speak freely. It features transcription, summarization, and recording capabilities, with the option to transfer complex inquiries to human operators. The service is built on a cloud environment provided by NEC Nexa Solutions, integrating technology from Decoding X to ensure security, data management, and compatibility with existing CRM or reservation systems.

In a related discussion on AI implementation, Shinichiro Sakane of Gen-AX emphasized the necessity of ‘structuring business processes’ before deploying AI agents. Speaking at AI Marketing Day 2026, Sakane noted that while AI can answer questions fluently, it cannot automatically execute complex tasks unless the underlying business logic and decision conditions are clearly defined and communicated to the AI.
